520 |a Due to the unique electronic structure of aluminum ions (Al3+ ) with strong Coulombic interaction and complex bonding situation (simultaneously covalent/ionic bonds), traditional electrodes, mismatching with the bonding orbital of Al3+ , usually exhibit slow kinetic process with inferior rechargeable aluminum batteries (RABs) performance. Herein, to break the confinement of the interaction mismatch between Al3+ and the electrode, a previously unexplored Se2.9 S5.1 -based cathode with sufficient valence electronic energy overlap with Al3+ and easily accessible structure is potentially developed. Through this new strategy, Se2.9 S5.1 encapsulated in multichannel carbon nanofibers with free-standing structure exhibits a high capacity of 606 mAh g-1 at 50 mA g-1 , high rate-capacity (211 mAh g-1 at 2.0 A g-1 ), robust stability (187 mAh g-1 at 0.5 A g-1 after 3,000 cycles), and enhanced flexibility. Simultaneously, in/ex-situ characterizations also reveal the unexplored mechanism of Sex Sy in RABs
